87 / 116 page  Programmable USB Port Power Controller with Charger Emulation Datasheet SMSC UCS1002 87 Revision 1.4 (07-16-13) DATASHEET 10.10 Preloaded Emulation Enable Registers The Preloaded Emulation Enable registers enable the charger emulation profiles used by the emulation circuitry. 10.10.1 BCS Emulation Enable - 20h The contents of this register are retained in Sleep. Bit 4 - DCP_EM_DIS - Disables the DCP charger emulation profile in the DCE Cycle. This bit is ignored if the M1, M2, and EM_EN control settings have selected DCP mode (see Table 9.1, "Active Mode Selection"). ‘0’ (default) - The BC1.2 DCP charger emulation profile is enabled during the Dedicated Charger Emulation Cycle. ‘1’ - The BC1.2 DCP charger emulation profile is not enabled during the DCE Cycle. Bit 2 - RESERVED - Do not change. This bit will read ‘1’ and should not be written to a logic ‘0’. Bit 1 - RESERVED - Do not change. This bit will read ‘1’ and should not be written to a logic ‘0’. Bit 0 - RESERVED - Do not change. This bit will read ‘0’ and should not be written to a logic ‘1’. 10.10.2 Legacy Emulation Enable - 21h The contents of this register are retained in Sleep. Bit 6 - LG7_EM_DIS - Disables the Legacy 7 charger emulation profile. ‘0’ (default) - The Legacy 7 charger emulation profile is enabled. ‘1’ - The Legacy 7 charger emulation profile is not enabled. Bit 5 - LG6_EM_DIS - Disables the Legacy 6 charger emulation profile. ‘0’ (default) - The Legacy 6 charger emulation profile is enabled. ‘1’ - The Legacy 6 charger emulation profile is not enabled. Bit 4 - LG5_EM_DIS - Disables the Legacy 5 charger emulation profile. ‘0’ (default) - The Legacy 5 charger emulation profile is enabled. ‘1’ - The Legacy 5 charger emulation profile is not enabled. Bit 3 - LG4_EM_DIS - Disables the Legacy 4 charger emulation profile. ‘0’ (default) - The Legacy 4 charger emulation profile is enabled.
